[Pseudoaneurysm of a branch of the internal mammary artery in a case operated on for aortic coarctation].

False aneurysm of the internal mammary artery (IMA) is a rare complication of closure of median sternotomy by peristernal wiring. In this report a case of a false aneurysm of a branch of the internal mammary artery following a surgical repair of a complex cardiac anomaly in a patient with a previously dilated mammary artery system for pre-existing coarctation of the aorta is described. In our opinion a special attention has to be given to the course of the IMA and its collaterals whenever a median sternotomy is required to treat an aortic coarctation or its associated diseases, considering the possibility of ligation of vessels at risk of being damaged by the sutures used for closure of the sternal and rectus sheath incisions.

[Correlation between electrocardiographic and echocardiographic findings in chronic aortic insufficiency].

Echocardiographic indices of left ventricular volume and mass and electrocardiographic indices of left ventricular hypertrophy have evaluated in 25 patients with chronic aortic regurgitation and in 10 normal subjects. When the patients with aortic regurgitation were subdivided in three groups with increasing evidence of left ventricular hypertrophy, the echocardiographic measures of left ventricular dimension and mass were also found to be increased, with statistically significant differences between patients and controls and among the three groups of patients as well. A specially constructed cumulative electrocardiographic index of left ventricular hypertrophy (Sokolow and Lyon's index plus Lewis' index plus strain pattern) is correlated with the left ventricular end-diastolic diameter (r = 0.65; P less than 0.001), cross-sectional area (r = 0.65; p less than 0.001) and mass (r = 0.75; p less than 0.001) better than the isolated electrocardiographic indexes.

[Echocardiographic features of the St. Jude Medical valve prosthesis (author's transl)].

The St. Jude Medical (SJM) valve is a new low-profile bileaflet prosthesis with central flow, low transvalvular gradients and low thrombogenicity. Echocardiographic features of 212 correctly functioning SJM prostheses implanted in 160 patients were studied. A SJM prosthesis echogram is unique for the presence of echoes from two hemidisks that come together when the valve opens and separate when the valves close. The movement of the two hemidisks is not always synchronous. A little asynchronism (less than 0.01 sec.) is possible as the valve begins to open. More pronounced asynchronisms are recorded in prostheses implanted in mitral position and specially when the R-R interval is longer than 1 sec. In this case partial or definitive mid-diastolic closure of the posterior hemidisk is frequent. On the contrary the anterior hemidisk always remains in maximum open position for the complete duration of the diastole. Opening and closing velocities of the valve are extremely variable. However, opening velocity, independent of where the prosthesis is implanted, is always slower than the closing one. The opening valve interval is 0.06-0.10 sec. in mitral position and 0.03-0.05 sec. in aortic position. Echocardiography is a very useful diagnostic tool for evaluating the efficiency of SJM prosthesis. Data obtained from echograms of prostheses implanted in mitral position prove that the inertia of the valve hemidisks is similar to that of natural valve leaflets.
